we can help improve your sight


If you have both cataracts and open-angle glaucoma, Dr. Collins may suggest the iStent Trabecular Micro-Bypass to treat your open-angle glaucoma. Dr. Collins is one of the first and most experienced surgeon’s in the Southwest Florida area to offer the iStent. With the implantable iStent, you may be able to forgo or greatly reduce the daily use of medicated eye drops while still lowering excess intraocular eye pressure.

The iStent is the smallest medical implant device in the world — it is 20,000 times smaller than the intraocular lens implant (IOL) used in cataract surgery! It is implanted in the eye during cataract surgery.

iStent provides a permanent opening through the blocked drainage channel, causing fluid to drain more easily and thus lowering intraocular eye pressure.


ECP is a laser treatment done at the time of cataract surgery that delivers a gentle type of light energy through a fine fiber optic probe. During the cataract operation, Dr. Collins or Dr. Friedrichs is able to use the same tiny incisions to remove the cataract, implant an intraocular lens, and perform the ECP procedure.


This procedure involves short bursts of energy to reduce pressure on the optic nerve in patients with primary open angle glaucoma. It may reduce dependence on drops and can be safely repeated many times.


MIGS (minimally invasive glaucoma surgery) procedures lower eye pressure in a safe manner with rapid recovery and minimal restrictions. Instead of creating an artificial drain in the eye, they unclog the natural drainage system of the eye and enhance drainage.

Dr. Friedrichs is able to offer MIGS with a new platform called the OMNI® Glaucoma Treatment System. This incredible advancement combines two procedures known as trabeculotomy and vasodilation of Schlemm’s canal in one hand-held device without the need for additional incisions. In the past, these procedures had to be done as part of cataract surgery. Thanks to the new advancements in technology, they can now be done separately as an outpatient procedure with little to no downtime.


In patients with primary open-angle glaucoma, identifying where blockage or resistance occurs within the conventional outflow pathway can be challenging. Targeting the trabecular meshwork alone, or isolating a single point, is not always enough to lower Intraocular Pressure IOP.


At Collins Vision, our expertly-trained ophthalmologists are able to address glaucoma with a variety of treatments, ranging from eye drops to surgery. The Xen Gel Stent is one of the latest breakthroughs in glaucoma treatment. 

What is the XEN Gel Stent?

XEN Gel Stent is a tiny gelatin implant designed to help bypass the blocked drainage system of the eye. It works by creating a small channel in the eye to drain fluid and help reduce the IOP. XEN is suggested for patients with open-angle glaucoma (also called refractory glaucoma) where previous surgical treatment has failed and/or medications (at maximum dosage) alone were insufficient.

The XEN Gel Stent is implanted in a minimally invasive procedure and can be done at the same time as cataract surgery, saving patients time and money. XEN has been described by researchers as a “hybrid” between microinvasive glaucoma surgery (MIGS) and traditional glaucoma surgery.

How does the XEN Gel Stent Work?

The XEN Gel Stent is tiny (about the size of an eyelash!) and is placed underneath the transparent tissue that covers the white of the eye. It is designed to stay in the eye permanently and can’t be seen or felt. Think of it as a tiny, clear tube and after implanted in the eye, it becomes soft and flexible.
